SURFACE HEAT TREATMENT OF FACING AND OTHER MATERIALS WITH CONCENTRATED SOLAR ENERGY
V. V. Pasichnyi and V. Ya. Berezhetskaya UDC 662.997:666.642 Surface treatment of building materials, ornamental ceramics, cover-coat enamels, blast-furnace and open-hearth slags, and natural stones of the basalt type has been carried out with the use of solar furnaces and their simulators for the purpose of obtaining protective-decorative vitreous and glazed coatings. The specific energy consumption and the optimum heat fluxes necessary to obtain high-quality coatings have been determined. The results of searching investigations testify to the fact that renewable environmentally safe concentrated solar energy can be utilized in industry and the national economy for surface heat treatment of different materials by melting them in the air.
